Electrical Characteristics
This table defines the PCI Express 2.0 (5 GT/s) AC specifications for the differential output at all transmitters. The parameters
are specified at the component pins. The AC timing specifications do not include RefClk jitter.

4. The chip’s SerDes transmitter does not have C
consecutive Tx UIs.
Transmitter collected over any 250 consecutive Tx UIs. The T
Tx jitter budget collected over any 250 consecutive Tx UIs. Note that the median is not the same as the mean. The jitter median
describes the point in time where the number of jitter points on either side is approximately equal as opposed to the averaged
time value.

Each UI is 400 ps ± 300 ppm. UI does not account for
spread spectrum clock dictated variations. See Note 1.
The maximum transmitter jitter can be derived as:

All transmitters must be AC coupled. The AC coupling
is required either within the media or within the
transmitting component itself.
